Text in Afrikaans / Selfmoord is 'n kontroversiele aangeleentheid wat beide omstanders en agterblywendes met onsekerheid vervul. 'n Belangrike rede hiervoor is dat dit 'n onnatuurlike afsterwe is wat teen baie mense se norme en waardes indruis. ldiografiese navorsing is onderneem om die belewenisse van agterblywende gesinslede te ondersoek aangesien hulle die eintlike slagoffers van 'n selfmoord is wat met 'n komplekse realiteit gelaat word. Die doel van die navorsing was om riglyne daar te stel vir die hantering en ondersteuning van hierdie mense. Vanuit 'n in-diepte literatuurstudie, het dit geblyk dat die grootste probleme waarmee agterblywendes gekonfronteer word, wentel random problematiese emosies, veroordeling deur omstanders en belewings van persoonlike onvermoe om te midde van intense rousmart selfaktualisering optimaal te volvoer. 'n Vraelys wat aspekte (socs dit uit die literatuurstudie geblyk het) inkorporeer, is opgestel en aan agterblywendes gegee om te beantwoord. Van die belangrikste elemente wat na vore gekom het, is dat intense verhoudingskomplikasies na 'n selfmoord figureer, dat agterblywendes 'n behoefte het om rouverwerking teen hul eie tempo te doen, dat agterblywendes verkies dat omstanders nie voortdurend die gebeure sal ontleed en soek na oorsake in die teenwoordigheid van agterblywendes nie en dat elke agterblywende persoon se roubelewing persoonlik en uniek is. 'n Hoofstuk is gewy aan 'n wye verskeidenheid terapeutiese tegnieke wat geimplementeer kan word tydens hulpverlening aan agterblywendes.

It causes both bystanders and survivors to feel insecure. An important reason for this is that it is an unnatural death which directly opposes the norms and values of the majority of people. ldiografic research has been undertaken to closely examine the experiences of suicide survivors as they are the real victims who are left to cope with a complex reality after a suicide. The objective of this study was to provide guidelines to effectively manage and render assistance to survivors. From an in depth review of available literature it appeared that troubled emotions, being denounced by bystanders and the inability to proceed with continued qualitative self-actualization are some of the most important problems survivors have to cope with. A questionnaire, incorporating significant aspects reported in literature, was compiled and given to survivors to complete. From their responses certain facets seemed to be problematic. Among the more problematic aspects were complicated interpersonal relations, the basic need to grieve at their own pace, the preference that bystanders avoid analysing the suicide and possible contributing factors (especially in the presence of survivors) and the recognition that each survivor's grief is personal and unique. A chapter has been devoted to a wide range of therapeutic techniques that can be implemented to facilitate the support given to survivors. The study also describes a case study as well as the progression of sixteen individual therapy sessions. Therapeutic intervention was mainly based on hypnotherapy as a form of relaxation therapy during which the focus is placed on problematic emotions and perceptions which prevent continued qualitative self-actualization. Educational Psychological guidelines along which assistance can be rendered by psychologists, teachers as well as other support services are given. This study not only confirms that the survivors are the actual victims of a suicide, but also that it is possible to assist these people to achieve optimal self-actualization through meaningful intervention. / Psychology of Education / D.

A roller coaster manufacturer became aware that improperly heat treated track couplings were sent to a construction site for assembly. Concerns were that suspect couplings might not meet the engineering specifications and could be vulnerable to sudden failure. A testing company in Oak Ridge, TN that specializes in in-situ and laboratory mechanical testing was contacted by the manufacturer for help in this endeavor. The construction company elected to enlist a local testing firm to perform field tests on the components instead of the company in Oak Ridge. The test methods used are incapable of providing quantitative results that could be measured to the engineering specifications, making it unlikely to identify anything but the worst material conditions. This study is an example that the need for accurate analysis is very important. The manufacturer reported that 60 couplings were replaced, but it is presently unknown how many should have been replaced.

A probabilistic methodology for the reliability analysis of composite rotor blades at the ply level was developed. The proposed methodology involves (i) the quantification of the uncertainties (physical, statistical and model) related to the material properties and the extreme aero-elastic loads based on experimental data as well as on 10 min load simulations respectively, (ii) the identification of the critical failure modes of the composite structure in terms of limit state functions and (iii) the selection of an appropriate reliability method to perform the analysis. It is pointed out that the reliability method should be able to handle the considerably large number of limit state function introduced by the ply level reliability approach and estimate the failure probability of the structure. To efficiently deal with the problem, an appropriate implementation of the Response Surface Method combined with crude Monte Carlo simulation was proposed. The methodology was implemented for two real rotor blade designs, namely a 30m Glass/Polyester and the 65m UPWIND reference rotor baled. Initially, calculations were performed for the first case study using a 3D shell FE formulation in a commercial probabilistic code. An efficient procedure was introduced to define the stochastic character of the concentrated loads acting on the 3D FE model starting from load time series of sectional stress resultants from aero-elastic beam simulations. For the first time such a detailed model was analyzed and assessed in a probabilistic base. Nevertheless, a considerable CPU time was in need for the performance of such a reliability analysis. The development of an efficient probabilistic tool capable to perform consecutive reliability analyses at the ply level of the composite rotor blade structure and prove valuable for the probabilistic design was carried out. To demonstrate the efficiency of the developed tool, the impact of various probabilistic modelling assumptions directly on the β-index value of a rotor blade design was studied. / Στην παρούσα διατριβή αναπτύχθηκε στοχαστική μεθοδολογία για την αποτίμηση αξιοπιστίας πτερυγίων ανεμογεννητριών από σύνθετα υλικά, στο επίπεδο της στρώσης, υπό ακραία στατική φόρτιση. Η προτεινόμενη μεθοδολογία περιλαμβάνει (i) την ποσοτικοποίηση αβεβαιοτήτων (φυσική, στατιστική και αβεβαιότητα μοντέλου) που σχετίζονται με τις βασικές παραμέτρους του πτερυγίου (υλικά και φορτία) στηριζόμενη σε ένα μεγάλο αριθμό πειραμάτων για τον προσδιορισμό των μηχανικών ιδιοτήτων του συνθέτου υλικού καθώς και 10-λεπτες αεροελαστικές χρονοσειρές για την ακραία στατική φόρτιση (ii) την αναγνώριση όλων των σημαντικών μηχανισμών αστοχίας της κατασκευής και την έκφρασή τους στη μορφή οριακών συναρτήσεων αστοχίας και (iii) την επιλογή μίας κατάλληλης μεθόδου αξιοπιστίας. Σημειώνεται ότι η μέθοδος αξιοπιστίας θα πρέπει να είναι ικανή να διαχειρίζεται ένα πολύ μεγάλο αριθμό οριακών συναρτήσεων αστοχίας όπως επιβάλει η ανάλυση αξιοπιστίας στο επίπεδο της στρώσης της κατασκευής. Για το σκοπό αυτό προτάθηκε μια κατάλληλη τροποποίηση της Response Surface Method τεχνικής η οποία συνδυάστηκε με την μέθοδο προσομοίωσης crude Monte Carlo. Η προτεινόμενη στοχαστική μεθοδολογία εφαρμόστηκε για την περίπτωση δυο πραγματικών πτερυγίων: ενός 30 m Glass/Polyester και του 65 m Glass/Epoxy (UPWIND) πτερυγίου. Η ανάλυση αρχικά πραγματοποιήθηκε σε γενικού σκοπού στοχαστικά εργαλεία κάνοντας χρήση τρισδιάστατου μοντέλου πεπερασμένων στοιχείων. Σημειώνεται ότι ο υπολογισμός των φορτίων από αεροελαστικούς κώδικες υλοποιείται πάντα στη βάση στοιχείων δοκού. Προτάθηκε επομένως διαδικασία για την στοχαστική αναπαράσταση των συγκεντρωμένων δυνάμεων που επιβάλλονται στο τρισδιάστατο μοντέλο πεπερασμένων στοιχείων του πτερυγίου στηριζόμενη σε χρονοσειρές εσωτερικών αντιδράσεων στη διατομή όπως εξάγονται από αεροελαστικους υπολογισμούς. Για πρώτη φορά σε αυτή την εργασία, πραγματοποιήθηκε η στοχαστική ανάλυση ενός τόσο λεπτομερειακού μοντέλου. Ωστόσο η παραπάνω προσέγγιση αποδείχτηκε αρκετά χρονοβόρα. Για το σκοπό αυτό αναπτύχθηκε υπολογιστικό εργαλείο ικανό να εκτελεί ένα μεγάλο αριθμό επαναλήψεων της προαναφερθείσας μεθοδολογίας και να φανεί χρήσιμο στο σχεδιασμό πτερυγίων με προκαθορισμένο επίπεδο αξιοπιστίας. Εξαιτίας της απλότητας της προετοιμασίας των δεδομένων εισόδου και της ταχύτητας επίλυσης, το νέο εργαλείο έδωσε τη δυνατότητα για τη μελέτη διαφόρων στατιστικών υποθέσεων που αφορούσαν τη δομική αξιοπιστία του πτερυγίου εξετάζοντας απευθείας τον δείκτη αξιοπιστίας β της κατασκευής.

The work presented in this thesis comprises the assessment of existing arch bridges with overlying backfill. The main objective is to estimate the load carrying capacity in ultimate limit state analysis. A case study of the old Årsta railway bridge is presented, serving as both the initiation and a direct application of the present research. The demand from the bridge owner is to extend the service life of the bridge by 50 years and increase the allowable axle load from 22.5 to 25 metric tonnes. The performed analyses show a great scatter in estimated load carrying capacity, depending on a large number of parameters. One of the factors of main impact is the backfill material, which may result a significant increase in load carrying capacity due to the interaction with the arch barrel. Based on theoretical analyses, extensive conditional assessments and the demand from the bridge owner, it was decided that the bridge needed to be strengthened. The author, in close collaboration with both the bridge owner and the persons performing the conditional assessment, performed the development of a suitable strengthening. The analyses showed a pronounced three-dimensional behaviour, calling for a design using non-linear finite element methods. Due to demands on full operability during strengthening, a scheme was developed to attenuate any decrease in load carrying capacity. The strengthening was accepted by the bridge owner and is currently under construction. It is planned to be finalised in 2012. The application of field measurements to determine the structural manner of action under serviceability loads are presented and have shown to be successful. Measured strain of the arch barrel due to passing train has been performed, both before, during and after strengthening. The results serve as input for model calibration and verification of the developed strengthening methods. The interaction of the backfill was not readily verified on the studied bridge and the strengthening was based on the assumption that both the backfill and the spandrel walls contributed as dead weight only. The finite element models are benchmarked using available experimental results in the literature, comprising masonry arch bridges with backfill loaded until failure. Good agreement is generally found if accounting for full interaction with the backfill. Similarly, accounting for the backfill as dead weight only, often results in a decrease in load carrying capacity by a factor 2 to 3. Still, several factors show a high impact on the estimated load carrying capacity, of which many are difficult to accurately assess. This suggests a conservative approach, although partial interaction of the backfill may still increase the load carrying capacity significantly. / Arbetet i föreliggande avhandling omfattar analyser av befintliga bågbroar med ovanliggande fyllning. Huvudsyftet är att uppskatta bärförmågan i brottgränstillstånd. En fallstudie av gamla Årstabron redovisas, vilken utgör både initieringen och en direkt tillämpning av föreliggande forskning. Kravet från broförvaltaren är att öka brons livslängd med 50 år, samtidigt som axellasten ska ökas från nuvarande 22.5 ton till 25 ton. Utförda analyser visar på stor spridning i uppskattad bärförmåga, beroende på ett stort antal parametrar. En av de främsta faktorerna är fyllningens egenskaper, vilken kan resultera i en markant ökning av bärförmågan p.g.a. samverkan med bågen. Baserat på teoretiska analyser, tillståndsbedömningar och krav från broförvaltaren beslutades att bron skulle förstärkas. En förstärkningsmetod har utvecklats i nära samarbete med broförvaltaren och personer som tidigare utfört tillståndsbedömningarna. Analyserna visar ett utpräglat tredimensionellt beteende, vilket har föranlett användandet av icke-linjära finita elementmetoder. Krav på full trafik under samtliga förstärkningsarbeten har resulterat i att dessa utförs enligt en föreskriven ordning, som ska reducera minskning i bär­förmåga under samtliga etapper. Förstärkningsförslaget godkändes av Banverket och är för närvarande under byggnation. Enligt plan ska dessa slutföras under 2012. Fältmätningar har använts för att bestämma det statiska verkningssättet under brukslaster, vilket visas ge goda resultat. Resulterande töjningar från passerande tåg har uppmäts i bågen, både före, under och efter förstärkning. Resultaten har använts både för att kalibrera beräkningsmodeller och att verifiera utförda förstärkningar. Samverkan mellan båge och fyllning har inte kunnat verifierats för den aktuella bron och de utvecklade förstärkningarna baseras på en modell där både fyllning och sidomurar endast utgör yttre verkande last. De framtagna finita element modellerna har jämförts med experimentella resultat från litteraturen, omfattande tegelvalvsbroar med ovan­liggande fyllning belastade till brott. Generellt erhålls god överensstämmelse om full samverkan mellan båge och fyllning antas. Om fyllningen istället endast betraktas som yttre last, minskar lastkapaciteten ofta med en faktor 2 till 3. Fortfarande uppvisar ett antal faktorer stor inverkan på bärförmågan, vilka ofta är svåra att med säkerhet bestämma. Ett konservativt betraktningssätt rekommenderas, även om delvis sam­verkan med fyllningen fortfarande kan öka bärförmågan avsevärt. / QC 20110426

Past studies on sands have shown that the shear strength measured in plane strain tests was higher than that measured in triaxial tests. It was observed that this difference changed with the friction angle &amp / #966 / cv at constant volume related to the mineralogical composition. In order to investigate the difference in strength measured in the wedge shear test, which approaches the plane strain condition, in the triaxial test, and in the shear box test, Anatolian sands were obtained from different locations in Turkey. Mineralogical analyses, identification tests, wedge shear tests (cylindrical wedge shear tests (cylwests) and prismatic wedge shear tests (priswests)), triaxial tests, and shear box tests were performed on these samples. In all shear tests, the shear strength measured was found to increase with the inclination &amp / #948 / of the shear plane to the bedding planes. Thus, cylwests (&amp / #948 / = 60o) iii yielded higher values of internal friction &amp / #966 / by about 3.6o than priswests (&amp / #948 / = 30o) under normal stresses between 17 kPa and 59 kPa. Values of &amp / #966 / measured in cylwests were about 1.08 times those measured in triaxial tests (&amp / #948 / &amp / #8776 / 65o), a figure close to the corresponding ratio of 1.13 found by past researchers between actual plane strain and triaxial test results. There was some indication that the difference between cylwest and triaxial test results increased with the &amp / #966 / cv value of the samples. With the smaller &amp / #948 / values (30o and 40o), priswests yielded nearly the same &amp / #966 / values as those obtained in triaxial tests under normal stresses between 20 kPa and 356 kPa. Shear box tests (&amp / #948 / =0o) yielded lower values of &amp / #966 / than cylwests (by about 7.9o), priswests (by about 4.4o), and triaxial tests (by about 4.2o) under normal stresses between 17 kPa and 48 kPa. It was shown that the shear strength measured in shear box tests showed an increase when &amp / #948 / was increased from 30o to 60o / this increase (about 4.2o) was of the order of the difference (about 3.6o) between priswest (&amp / #948 / = 30o) and cylwest (&amp / #948 / = 60o) results mentioned earlier. Shear box specimens with &amp / #948 / = 60o, prepared from the same batch of any sample as the corresponding cylwests, yielded &amp / #966 / values very close to those obtained in cylwests.

宗教倫理即是以宗教信仰為核心而建構的倫理道德體系。一貫道信仰中，道親往生後，家屬處於不穩定狀態，宗教倫理能提供死者一個終極關懷，即是回歸理天的彼岸世界。對家屬而言，一貫道道場倫理給予物質與精神面的支助，強化此岸世界的倫理關係，人與人與間更緊密的連結起來。 本論文從一貫道內部經典與外界研究的文獻整理，來分析有關宗教儀禮的教義與實踐，另外，從各組線的訪問與田野調查比較其奠禮的發展過程與理念基礎。此研究首先探討一貫道教義的基本觀念，再對應理天倫理與道場倫理的互動關係，然後對奠禮儀式的人事安排、流程與意涵加以剖析，最後與民間奠禮做一比較，可觀察一貫道禮儀在禮俗上，經過吸收與轉化後對社會的貢獻程度。總結，一貫道奠禮可以說明宗教倫理對失序的家庭倫理有支持、整合的功效。 / Religious ethic is constituted as a frame of moral philosophy that centered by religious beliefs. In the beliefs of I-Kuan Tao, Tao members’ death lead their families fall into a instable status; therefore, religious ethic is seeking to a situation of providing flatliner a ultimate concern, which means after death, the spirit will go back to “Li Tian” - Heaven. For those Tao members who face their families’ death, Tao ethic could offer the support not only on substance but also spirit side, so it improves the ethical relationship in the shore world, and link up all people more closer. This thesis was done via researching from inside scripture of I-Kuan Tao and outside studies from relative scholars to analyze about creed and practice of religious ritual. In addition, the thesis was also completed by doing interview and fieldwork of other branch of I-Kuan Tao on the development of the laying ceremony. The thesis started with the basic concept of I-Kuan Tao’s dogma, and then correspond the interactive relation between Heaven ethic and temple ethic. Subsequently analyze the ritual of laying ceremony of personnel arrangement and procedure and significance. Finally the thesis show the comparison of I-Kuan Tao laying ceremony and folk type to show I-Kuan Tao’s way has contributed to the society. In conclusion, I-Kuan Tao’s laying ceremony can interpret that religious ethic the function of supporting and integration for the domestic disorder.

Digital image correlation techniques (DICT), a non-contact deformation measuring technique based on gray value digital images, have become increasingly used over the last years. By using the DIC technique during a tensile test, the deformation behavior of different engineering material under an applied load can be determined and analyzed. Digital images, acquired from a tensile test, can be correlated by using DICT software and from that the local or global mechanical properties can be calculated. The local or global mechanical properties determination of a flat test specimens are based on the displacements or changes in a previous stochastic sprayed or natural pattern. The used material for this purpose is cast silicon (Si) based aluminium (Al) component, designated as AlSi7Mg0.3 (Anticorodal-78 dv). The hypoeutectic Al- Si alloy is widely applicable for engine constructions, vehicle and aerospace constructions, shipbuilding, electrical engineering and constructions for food industry. There are many microstructural parameters in a binary system Al- Si alloys, which the mechanical properties can be depended on, for instance phase distribution, Secondary Dendrite Arm Spacing (SDAS), morphology of Si particles (Roundness) and microscopic defects or pores. All these parameters can contribute to enhance the proper mechanical performance (e.g. Strength and ductility) in the Al-Si cast components.

The traditional reserve estimation by an insurance company is based on the aggregated data. However, new trend is to utilize all the information available and analyse each claim separately. This way the application of claims specific features, such as non-proportional reinsurance or policy limits, is possible. The aim of this thesis is to construct the reserving model based on the individual claims. Following the recent legislative changes, the reserve risk has been redefined from ultimate claim horizon to a one-year risk horizon. Hence, the next task is to setup simulation model to calculate one year horizon reserve risk by updating the estimates based on new observations collected over one year. This is a typical task for Bayesian approach, therefore the model components are estimated using the tools of Bayesian statistics.
